of the inlet water-pipe. The stufling-box 01 should befixed centrally over the stuffing-box on the valve-casing E, so that the plunger (1 and stem e will range in line with each other.

F is'a taper nozzle fixed in the head I) of the cylinder 13 and extending centrally into the inner end of the Outlet water-pipe G, so as to leave an annular opening between the said nozzle and outlet-pipe.

The operation of my invention is as follows: On opening the stop-cock d to let a stream of water pass through the pipe D into the waterspace 0 of the heater the current of water passing through said pipe will pass over the opening of the branch (1 in a line at right angles to the axis of said opening, and, following a well-known law of fluid pressures, the current will produce a reduction of the press- To all whom it may concern:

Be it known that 1, JAMES PARK, of Troy, in the county of Bensselaer and State of New York, have invented certain new and useful Improvements in \Vater Heaters and Feeders, of which the following is a specification.

My invention relates to improvements on the class of heaters and feeders wherein the water is heated and fed into a boiler, or othervessel or apparatus, by means of a currentof live steam; and the object of my improvements is to provide the apparatus with a steam-valve that will automatically open and close by the opening and closing of the water-supply valve, as hereinafter described. This object I attain by means of the mechanism illustrated in the accompanying drawing, which forms part of this specification, and which contains a longitudinal section of my apparatus, with a porure (in said branch) acting against the innerv tion of the pipes and fittings shown in side end of the plunger d and, immediately on elevation. 1 this reduction of the pressure, the steam, acting As shown in the drawing, A is the outer; against the under side of the valve 6, will force cylinder or shell of the heater. 7 I the latter upward, and thus permit a current B is the inner cylinder for containing steam. of steam to pass into the chamber in cylinder Said inner cylinder is secured .to the head a B, wherein a portion of the steam will be utilof the shell, and is smaller and shorter than the ized for'heating the water in the water-space shell A; a water-space, O, is thus formed be- O, and then the current of steam, passing out 75 tween the cylinders A and B and the heads a" of the cylinder B through the nozzle F, will and b.
